There's some impassioned debate going on in the comments on the post about the couple in Texas failing to surrender a foul ball to the weeping child beside them. What are the real rules, here? Possession is nine-tenths of the law? Children first? What's the right thing to do to avoid the censure of Michael Kay and legions of people on the Internet? Next time you find yourself in the vicinity of a foul ball, just consult this step-by-step chart to find out if you're supposed to keep it. (Note: If your ticket is exactly $75, follow the "more" arrow.)
